The evolutionary history of ultra-compact accreting binaries. I. Chemical abundances and formation channel of the eclipsing AM CVn system ZTF J225237.05-051917.4 from HST spectroscopy

W. Yu, A. F. Pala, T. Kupfer +33

AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf (WD) primary accreting from a H-deficient donor. They are important as potential prog…

Constraints on an optical counterpart for the long-period radio transient GPM J1839-10

Ingrid Pelisoli, A. J. Brown, N. Castro Segura +14

Long period radio transients (LPTs) are periodic radio sources showing pulsed emission on timescales from minutes to hours. The underlying sources behind this emission are currentl…

Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii

Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56

The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…

A Sibling of AR Scorpii: SDSS J230641.47244055.8 and the Observational Blueprint of White Dwarf Pulsars

N. Castro Segura, I. Pelisoli, B. T. Gänsicke +21

Radio pulsating white dwarf (WD) systems, known as WD pulsars, are non-accreting binary systems where the rapidly spinning WD interacts with a low-mass companion producing pulsed n…

A targeted search for binary white dwarf pulsars using Gaia and WISE

Ingrid Pelisoli, T. R. Marsh, G. Tovmassian +24

After its discovery in 2016, the white dwarf binary AR Scorpii (AR Sco) remained for several years the only white dwarf system to show pulsed radio emission associated with a fast-…

V498 Hya, a new candidate for a period bouncer Cataclysmic Variable

Gagik Tovmassian, Keith Inight, Anna Francesca Pala +5

V498 Hya (SDSS J084555.07+033929.2) was identified as a short-period cataclysmic variable (CV) by the Catalina Real-Time Transient Survey (CRTS) in 2008. The superhump period was m…
